| description | Use when a coding agent must design, scaffold, implement, or verify an iOS or macOS SwiftUI interface with Apple-platform state, accessibility, availability, testing, and Xcode evidence. |
Build SwiftUI Interface
Use Memi to establish the Apple-platform contract before editing source. Pair this skill with OpenAI's build-ios-apps plugin skills when they are installed and the task needs simulator, profiling, App Intents, or detailed framework guidance.
Compact preflight
npx -y @memi-design/cli@2.7.8 ios brief --platform ios --intent "<task>" --detail compact --json
Inspect the actual project next: deployment target, Swift language mode, shared schemes, local components, assets, navigation, state ownership, test targets, and nearby implementation patterns.
File contract
Preview every generated byte before writing:
npx -y @memi-design/cli@2.7.8 ios scaffold FeatureName \
--kind screen \
--module AppModule \
--output-root Sources \
--tests-root Tests \
--json
Use --write only after the paths and source match the repository. Memi writes a spec, SwiftUI view, preview, screen model when needed, and Swift Testing file. It does not mutate .xcodeproj or .xcworkspace, and it refuses silent overwrites.
Implementation rules
- Reuse local SwiftUI components and semantic assets before adding primitives.
- Keep state ownership narrow; keep I/O and expensive work out of
body.
- Define loading, empty, populated, error, Dynamic Type, VoiceOver, reduced-motion, and dark-appearance states.
- Gate newer APIs. Liquid Glass requires an iOS 26+ branch and a behaviorally equivalent fallback.
- Treat June 2026 APIs by their documented availability; do not invent an iOS version label.
- Preserve the existing architecture and project-generation workflow.
Verification receipt
Run the repository's canonical commands. When none exist, discover shared schemes and explicit destinations with xcodebuild -list -json and xcrun simctl list devices available, then build and test the smallest target.
Report exact commands, files, deployment assumptions, simulator flow, accessibility states, and anything not executed. A source review is not simulator proof, and a simulator build is not signing or App Store proof.
